We got Aiden a little toolbox type Fisher Price toy that has shapes and a hammer and all that boy type fun... and of course, Alli had to test it out first today while bro was napping.
She would grab a shape, show it to me, and I would name it. I know that she knows a lot of the shapes, she knows and identifies squares, circles, triangles, stars, hearts, etc. She picked up another shape and handed it to me. I definitely was not expecting her to know what it was, so I just told her, "Oh, this a stop sign shape!" She matter-of-factly said back to me, "No mama. Octagon." Wow.
Mommy may need to brush up on her Spanish, her trigonometry, and who knows what else... this kid is just too smart sometimes.
